ABSTRACT
Objective@#To understand the natural carriage status of multidrug resistant gram-negative bacteria in ICU medical personmel and control growp of 69 hospitals in Tianjin.@*Methods@#From April 2007 to October 2016, 2902 samples of nasal vestibule and hand swabs were collected from 1296 ICU medical personmel and 155 non medical personmel (control group) , and 14 kinds of antimicrobial agents were used to test the sensitivity of gram-negative bacilli.@*Results@#332 Gram-negative bacteria were isolated from medical personmel, of which 139 were multidrug resistant; 70 gram-negative bacteria were isolated from control group, and 20 of which were multidrug resistant. There was no significant difference (P>0.05) in the incidence of nasal vestibular colonization between medical personmel group (231/1296) and control group (32/155) . The control group (38/155) had a higher rate of hand bacteria carriage than medical staff group (101/1296) (P<0.01) . The proportion of multidrug resistant gram-negative bacteria was 28.57% (20/70) in control group, which was significantly lower than medical personmel group (41.87%, 139/332) (P<0.05) .@*Conclusion@#For the nasal vestibule, the medical personnel and control guoup have the same gram-negative bacteria carrying rate, but the multidrug resistant bacteria isolation rate from the medical staff group are significantly higher which may due to vocational contamination of pathogen in ICU; while the gram-negative bacteria in the hands of the medical staff group are significantly lower than those of the control group, which might attribute to the difference of hand sanitation technique of two groups.
